The Arctic and the Antarctic are privileged locations for observers interested in understanding how our world is shaped by the forces of nature and the workings of history. These areas have inspired countless humans to undertake epic expeditions of discovery and have witnessed both great triumphs and miserable defeats. As a planetary litmus paper it is at the poles we can detect the effects of natural oscillations and human activities on the global ecosystems.

028 Snowmobiles
Polar areas are often covered with snow for a large part of the year and there snowmobiles can take the place of cars, small trucks and motorbikes. The evolution of the snowmobile begins with the adaptation of existing vehicles, like the Ford model T, to slide on the snow with skis under the front wheels. The invention of an adaptable caterpillar track, the Kégresse track allowed better traction than wheels and was the logical step towards the modern Ski-Doo and similar brands like the minimal Larven. Future development of the concept include higher power, increased safety, greater comfort and a quieter and less polluting engine.
